In the construction of the machine asshown the numerals 10, 11 designatesupporting wheels, one slightly in advance of the other on a transverseline. The wheels l0, 11 are arranged to travel in parallel lines butwith their axes in parallel planes transversely of the machine. Thewheel 10 also has the function of a traction wheel. A casting 12 isprovided and is fixed to the bottom of a beam 20 intermediate of theends of said beam. See Figs. 10 and 6. The casting 12 is formed with atransverse aperture and a horizontal end portion 13 of an arch 14extends through and is fixed in said aperture adjacent the beam. Thearch 14 preferably is made of metal tubing, such as gas pipe, and isformed with a horizontal end portion or ournal 15 on its end opposite tothe end portion 13. The horizontal end portion or journal 15 of the arch14 serves as an axle for the wheel 11. A bell-crank lever 16 is providedand is formed with a Worm gear 16 on the upper end portion of its upperarm. The bell-crank lever 16 is fulcrumed on an arm l6 depending fromthe casting 12. A journal or stub axle 17 is formed on and extendsoutwardly from the lower end portion of the bell-crank lever 16 andserves as an axle for the wheel 10. The worm gear 16 is engaged by aworm 18 on a rod 19 journaled on the beam 20 and provided with a handwheel 21 near the forward end portion of said beam. The beam 20 isarranged between and approximately parallel with the lines of travel ofthe wheels 10, 11.

It is the function of the worm 18, rod 19, hand wheel 21, lever 16 andtheir connections to raise and lower and hold the arch 14 and beam 20relative to the horizontal plane of the axles 15, 17 of the supportingwheels. A bar 23 is fixed at one end to the beam 20 and projectslaterally therefrom across the path of travel and in front of the wheel11 and a bar 24 is attached at its rear end to the arm 15 of the arch14, adjacent said wheel, and extends forward to the bar 23 andterminates opposite the forward end of said beam. A rake frame 25 ismounted in an oblique position between the wheels 10, 11. The forwardouter end port-ion of the rake frame 25 is attached to the extremity ofthe bar 23, the central portion of said rake frame is suspended from thebar 24 and the arch 14 and the rear inner end portion of said frame issuspended by a bearing plate 25 of any suitable construction connectedto the rear end of the beam 20. A rake shaft 26 is mounted for rotationat one end in the outer end of the rake frame 25 and at its other end inthe bearing plate 25 Spiders 26 are mounted rigidly on the rake shaft 26within the frame 25 and rake heads 26 are journaled in the extremitiesof the arms of said spiders. Rake teeth 26 are mounted on the rake heads26 and occupy approximately vertical planes depending from said heads. Apinion 2'? is mounted rigidly on the bearing plate 25 and the rear innerend portion of the shaft 26 extends through an aperture in the center ofsaid pinion. Pinions Q8 of approximately the same diameter as the pinion27 are mounted rigidly on end portions of the rake heads 26. Pinions Q9of approximately double the diameter of the other pinions are mountedloosely on stub axles 29 carried by the spider 2S nearest to the bearingplate 25". The pinions 29 mesh with the pinions 27 and 28 in the mannerillustrated in Fig. 7, thus forming an epicyclic gear or train whichmaintains the vertical positions of the rake teeth 26 in the travel ofthe rake heads 26 around the shaft 26. such travel being occasioned bythe fixed relations of the spiders on the rake shaft and the rotation ofthe latter as hereinafter described. A tongue 30 is pivotally connectedto a cross-head 31 mountet between and fixed to the forward ends of thebeam 20 and bar 2% and a seat 532 is supported on said cross-head. Meansshould be provided for maintaining and effecting adjustment of thetongue relative to the beam :20 and bar ill, and to this end I ha \eprovided a lever 33 of bell crank form fulcrinned on the cross-head 31.The short arm of the lever 33 extends forward parallel with the tongue80 and is connected at its extremity to said tongue by a link 34:. Thelever 33 is adapted for manual actuation and is held in any adjustedposition by a segmental rack 35 on the cross-head 31 engaged by detentdevices 36 of conventional form carried by said lever. Thus when theupper end portion of the lever 33 is moved rearwardly it permits thefulcrum of said lever to descend, and by this means raises the rear endof the beam 20 and lifts the rake from the ground. A short shaft 37 is journaled in and transversely of the casting 12 beneath the beam 20 and aclutch member 38 is fixed to the outer end portion of said shaft. Thisclutch member 38 may be simply a pin extending through the shaft andprojecting at either end therefrom. A hub 39 is mounted loosely on theouter end portion of the shaft 37 and is formed with a clutch member onone end adapted to engage the clutch member 38 when said hub is rotatedforwardly. A sprocket wheel 40 is fixed to the hub 35) and is connectedto and driven by a spl'Otkil wheel ii-l on the wheel 10 by a sprocketchain ir bevel gear 43 is mounted on the inner end portion of the shaft3?. it clutch lever la: is fulcruined on an ear l-l extending outwardlyfrom the casting The ear ti carries a segmental rack eti adapted to beengaged by detent devices l-l" of conventional form on the lever fl. Thelower end portion of the lever t is bifurcated and embraces and engagesthe hub if. Through the use of the lever Hi and its connections the hub39 may be disengaged from the clutch member 38, thus disconnecting thesprocket wheel 40 from the shaft 37.

A shaft as is disposed longitudinally of the beam 20 and adjacent theinner face of said beam and is journaled at one end in an angle plateadj ustably mounted on the inner face of the casting 12. The oppositeend portion of the shaft l5 is journaled in a bearing arm at; fixed toand depending from the rear end of the beam 20. A bevel gear at? on theforward end of the shaft T5 meshes with and is driven by the bevel gearA bevel gear lS on the rear end portion of the shaft 45 meshes with anddrives a gear t?) on the rear end of the rake shaft 26. The bearing armalt extends downward from the beam 20 and a stub axle l6 is fixed to orformed on the lower end portion thereof and extends rearwardly therefrom. A combined gear and sprocket wheel do is mounted on the stub axle-16 and the gear thereof meshes with and is driven by the gear lt) onthe rake shaft 26. An arm is mounted loosely on the rear end portion ofthe stub axle ate and extends laterally and down 'ardly therefrom. Thearm 50 is removable and replaceable relative to the stub axle l6 and hasa limited movement of oscillation thereon. The arm 50 is upheld by ahook or rest 46 on the bearing arm at), and may move upward therefrom. Ahearing box 51 or journal bearing is formed on the outer end portion ofthe arm 50. An arm 53 is removably and replaceably mounted on theextremity of the end portion 13 of the arch ll preferably by insertingone end of said arm in said end portion and securing the same by a remoable pin 54. The arm 53 extends rearwardly and outwardly across and atthe rear of the wheel 10 and a boxing or journal bearing 55 is fixed tothe extremity thereof. The box or journal bearing 55 is removable andreplaceable relative to the extremity of the arm and normally is securedthereto by a removable pin 56. The boxes or journal bearings 51,preferably are in the same horizontal plane and in alinement in the pathof advance of the machine.

An elevator shaft 57 is journaled in the boxes or journal bearings 51,55 and side boards 58, 59 are carried at their lower ends 011 saidboxes. A cable 60 is forked at its rear end and attached to the sideboards 58, 59 near the upper ends thereof, and said cable extendsthrough a guide sheave 61 mounted on the beam 20 to and is adapted to bewound on a drum 62 preferably mounted on the bar 24: adjacent the seat32. The drum 62 is adapted for manual actuation through the medium of acrank 63 thereon, and may be held against rotation in one direction by apedal-operated detent ea engaging a ratchet 65 on the drum, in orderthat said drum and cable may carry the weight of the elevator about tobe described. It is the function of the cable 60, drum 62 andconnections to adjust the inclination of the elevator. A carrier head,or carrier heads, may be mounted on the shaft 57 and an endless carrier66 is mounted around and driven by said head or heads, and also extendsaround a shaft 67 in and connecting the upper ends of the side boards58, 59. Cross-bars 68 connect the side boards 58, 59 between the shafts57 and 67 in conventional form. A bar 69 extends across the upperportion of the elevator and is journaled by means of cranks 70, 71 onits ends in the side boards 58, 59. Pressure bars 72 are pivoted attheir upper ends on the straight body portion of the bar 69 and extendlongitudinally of and above the carrier to points of rest on and slidingengagement with a rod 73 on the beam 20. It is the function of thepressure bars 72 to ride on and hold the hay being elevated on thecarrier and the crank formation and pivotal mounting of the bar 69 isfor the purpose of permitting upward movement of said pressure barsunder the in fluence of increased loads on the carrier, the slidingengagement of the ends of the pres sure bars on the rod 78 permittinglongitudinal movement of said bars and consequent rocking of thesupporting bar. A sprocket wheel 7 4c is mounted on the rear end portionof the shaft 57 and is connected by a chain to the sprocket portion ofthe wheel 46". Thus is a driving connection established between theshaft 45 and the elevator shaft 57 susceptible of driving the elevatorand elevating hay thereon. The arm 50 may be lifted out of the hook 46and removed with the gear 16 from the stub axle 46, and the elevator,including the side boards 58, 59, shaft 57, chain 75, and devicescarried thereby be lifted away from the bearing 55. The arm 53 also maybe removed from the end portion 13 of the arch 14. This done, the rakemay be operated independent of and without the loader when desired.

In practical use of the machine the combined rake and loader is advancedacross a field alongside of a wagon (notshown). The traction of thewheel 10 is conveyed through the sprocket gearing and bevel gearing todriving the rake and elevator in the desired directions. Thesidede1ivery rake accumulates and bunches the hay at the foot of theelevator and said elevator CO11- veys the hay to the wagon. Theinclination of the elevator is controlled through the cable 60 and drum62. The relation of the foot of the elevator and the base of the rake tothe surface of the ground is controlled by adjustment of the rod 19 andlever 33.
